EXP-TBA

Guardian Telecom EXP-TBA Explosion Proof Talk/Back Stations provide easy to operate paging with the versatility of a hands free slave speaker in Class I & Class II, Division 1 Hazardous Areas.

The EXP-TBA delivers reliable point-to-point communication in harsh, industrial environments such as on drilling rigs between drill floor and monkey board or anywhere where hands free communication is required from slave operator end.

The EXP-TBA has total system flexibility in order to adapt to station location, with the use of either internal microphone & faceplate PTT switch or master speaker as microphone & remote PTT switch.

A post announcement tone can be programmed (internal) to indicate end of page from master station to the slave speaker. An optional switch can be wired at the slave speaker to activate a ring signal at the master station to request communication.
